- Synopsis
- The transmission of internal force between concrete and reinforcement and their displacement gap are called as bond stress and slip, respectively. The bond constitutive laws are defined as the relationship between bond stress and slip. There are lots of proposed types of bond constitutive laws, so it is necessary that the laws should be selected carefully to adopt in finite element analysis. Japan Concrete Institute organized the Technical Committee for bond problems to clarify the information about bond constitutive laws and propose the appropriate applications of the laws. Some of committee activities such as meso-scale analysis, review works for previous papers and analysis results for tension-stiffening effect are introduced.
